The Duchess of Cambridge was alleged to have been targeted by private detective Jonathan Rees on behalf of the newspaper while she was Prince Williamâs girlfriend, according to The Guardian newspaper.

In the House of Commons, Labour MP Tom Watson said the Metropolitan Police had paperwork that showed Rees was, âillegally targeting members of the royal family, senior politicians and high-level terrorist informersâ.

He said the forceâs Operation Weeting, which is investigating the scandal, had told him the paperwork was outside the inquiryâs terms of reference. âI believe powerful forces are involved in a cover-up,â he added.

Mr Cameron said police were able to look at any evidence they find.

Scotland Yard said it had received a number of allegations of breach of privacy that fell outside the remit of Operation Weeting that it was considering.

News Of The World publisher News International called Mr Watsonâs claims âwholly inaccurateâ and said it had not been asked by police about Mr Rees.
